Backup and Instant Recovery with Azure Stack HCI

There are numerous benefits to deploying a hyper-converged infrastructure (HCI) system: scalability, performance, flexibility, security, and in most cases, management. An HCI deployment is suitable for edge, remote, or branch-office environments or large enterprises with the ability to easily scale storage requirements from TBs to PBs. Even more importantly, HCI can be rolled out on-premises, in a public cloud, or as an integrated hybrid solution. In fact, many customers use the same architecture for mass storage in PBs while running a VM solution.


These same systems can be deployed in a high-availability (HA) HCI configuration where the backup and instant restore are possible on the same platform. Azure Stack HCI offers an HA solution where it’s possible to scale to PBs of storage while experiencing high performance. There are quite a few backup and recovery solutions available on the market today. Azure Stack HCI has a few listed on the Marketplace, but for this review, we used Veeam Instant Recovery software. Tools such as this both modernize and accelerate disaster recovery plans, ensuring the immediate availability of a single VM or an entire data center.

Although backup and disaster recovery are typically two related, but separate notions, there’s the infrastructure backing up the data center, and then there’s the offsite infrastructure to failover to in the event of a disaster. The concept we’re exploring here is a little bit of a hybrid, essentially empowering the backup infrastructure to do more than it has in the past. In this model, the infrastructure can serve as a traditional target but configured with enough oomph, it can also serve as an on-prem DR site. This buys backup admins time while they evaluate the severity of the attack, outage, or mistake that’s led to the current problem. Getting enough power to run VMs at scale in a backup appliance is architecturally tricky, though, which is why HCI provides an interesting path.

HCI solves a lot of problems in the data center. It’s simple to deploy and manage, but scalability can be a problem in many architectures. With vSAN, for instance, storage and compute are coupled together, making it an inefficient choice for this role, that’s even forgetting about the cost for the moment. Thankfully, there are other options.

Azure Stack HCI Backup and Instant Recovery

DataON is a leading provider of Azure Stack HCI solutions. We’ve worked with them many times, most recently near the end of last year when we checked out their latest appliances. For this particular use case, though, DataON has put together something that’s pretty interesting. They’re using a pair of their HCI appliances for HA, coupled with a 60-bay Western Digital JBOD. The result is high-capacity storage that is resilient, cost-effective, and can be configured to meet any performance or capacity need.

DataON and Veeam Instant Recovery

 During disaster recovery, access to the backed-up data is the first step, and the second step is how to best leverage that data. If that data is inside a traditional backup appliance, chances are there will be a long recovery process accessing the data and trying to recover applications. Backup data is typically not residing on a storage appliance capable of running those applications. Veeam Backup and Recovery will help mitigate some of those issues with technologies such as Instant Recovery, allowing users to bring VMs and applications online immediately and keeping them online during a migration process to primary storage.

In our setup, we kept the backup storage close to our DataON Azure Stack HCI cluster through an attached Western Digital Ultrastar Data60. This provided the dense storage required for backups, with performant hosts on the front end capable of leveraging that storage in the event of a disaster recovery scenario. In such a situation, the most recent backups are restored with Instant Recovery, which allows them to run from the Ultrastar Data60 JBOD, with cache provided by the Azure Stack HCI cluster, and migrates live to production storage. While this process won’t fully replace the production storage performance capabilities, it helps to build a better bridge to get the applications online immediately, run well, and quickly move back to production storage.


In our scenario, we leveraged a production environment across 4x DataON AZS-6112 hosts, which backed up to a DataON Azure Stack HCI cluster running on 2x DataON K2N-216 hosts connected to the WD Ultrastar Data60 JBOD. The recovery Azure Stack HCI cluster was modestly-equipped with 2x Intel® Xeon® Bronze 3204 CPU @ 1.90GHz and 6 cores, 128GB of RAM, and 4x 1.5TB of Intel Optane SSDs. To test recovery performance, we built out 10 VMs, or 5 VMs per host, each having a raw data drive of 395GB of storage. These VMs each had 2 vCPUs, and 2GB of RAM assigned, with a focus on balancing CPU utilization on the recovery hosts. These VMs were brought online, and a 50GB workload was performed on each VM, simulating work during an Instant Recovery process before migrating the VMs back onto production storage.


With Veeam Instant Recovery, as the data is being used and writes come in, they go into a cache buffer which improves performance. We leveraged VM Fleet to build our set of VMs and test them in a before and after scenario, first inside the production environment and next in our Instant Recovery environment. The performance we measured leveraging the direct-attached Western Digital Data60 JBOD to our DataON K2N-216 Azure Stack HCI cluster was phenomenal.

Initial read data was slower until new write activity brought data into flash, but once it was inside cache, the speeds matched the performance of our production environment.



Final Thoughts

 The DataON Azure Stack HCI solution for backup and instant recovery ticks all the boxes for a solid, integrated HCI solution. The strong partnership with Microsoft, Western Digital, and Veeam delivers a resilient, cost-effective system that beats all other HCI HA solutions on the market today. This is a high-capacity storage system with configuration flexibility to satisfy on-prem, hybrid-cloud, or public cloud installations.

The flexible architecture of the DataON Integrated System delivers an optimized solution in size & performance with all-NVMe flash storage, including the convenience of pre-installed software, integrated drivers, and firmware updates. Simple to deploy and procure, it’s ideal for customers who require turnkey solutions with little deployment effort from IT staff.

DataON Integrated Systems are powered by 3rd Gen Intel® Xeon® Scalable processors, combining Intel® technology with Azure Stack HCI to provide a powerful platform for data center modernization. Together they enable organizations to modernize their infrastructure, start or extend their hybrid cloud journey, and consolidate virtualized workloads.

The DataON Integrated System architecture allows customers to scale up before having to scale out, making it cost-effective with plenty of room to grow. The solution was simple to implement and provided incredible numbers during our “instant recovery” when we erased our production drives, initiated recovery and migrated the VMs back to the production drives.

While most are familiar with dedicated backup appliances, the notion of a more flexible backup solution leveraging HCI isn’t as well known. Through this paper, we’ve shown how modern infrastructures can benefit from HCI which allows for flexibility in system design. With this kit from DataON we combined a number of technologies to deploy a high-performance, yet cost-effective, HCI backup and recovery solution.

To prove it’s not just an assembly of hardware, we put the DataON build to work with Veeam, targeting the performance of their Instant Recovery feature. The results are evident with our instantly recovered VMs performing the same on the Azure Stack HCI backup infrastructure as their primary location. While it can be argued that adding Optane SSDs to these systems is “unfair,” we would suggest a backup infrastructure that allows for such a thing is fantastic.

We’re in an era where organizations need to be able to do more than just backup and recover. Data availability is a business requirement in more and more use cases. Azure Stack HCI provides a tremendous opportunity for consolidation while still meeting expanding data-centric data needs.
